<h1>Questions in the questionnaire</h1>

<p><b><u>What is the recommended number of questions?</u></b></p>

<p>Take, for example, a comprehensive examination of calculations. The test consists of a single integral. Student A, which yields an acceptable manner, makes a miscalculation that eventually undermines its outcome. Student B, whose performance is mediocre, is fortunate to have memorized the comprehensive solution that specifically as he took a last look at his notes. In the end, the information you give us the test results will be most wrong. How easy it would have been, simply put not one but ten integral to better estimate the level of each: Student A had failed in the first, but it is hoped that the other had demonstrated its technical management, student B had successful one, but the rest of the exercises had ended by betraying their true level of learning.</p>

<p>So <b>if there are more questions of the same type, more reliable will be our test </b>, always within reasonable limits: beyond a certain amount, put more items just increases reliability, and what we do do get is more tedious proof, totally unnecessary. In any case, it would establish a minimum of 20-25 <b>exam questions</b>.</p>
